How Do I Ship My Products?

I'm sorry, if i missed it somewhere, but how do you ship cookies? Or ship anything edible? How do I package something that is in a clear plastic box so that it doesn't get crushed?

Are there any across the state lines regulations that I need to be aware of? Do laws as far as operating a home kitchen in my state matter across borders? Is there anything I need to do in this department? How does it work selling things online? Do you include shipping in the total for the cookies? I see a lot of people doing that.

Sorry for asking so many questions. I'm completely new to shipping. I never have shipped anything much less a cookie before. Don't know why, just haven't.

If anybody has any tips, advice, a forum post on the subject it would be greatly appreciated.
